quantum mechanical treatment on sp hybridisation of carbon atom

Illustration: Methane - CH 4 In methane, the carbon atom undergoes sp 3 hybridisation and forms four sp 3 hybridised orbitals. Each of the hybrid sp 3 orbitals of carbon overlaps axially with half filled '1s' orbit..

Hybridisation is the phenomenon of redistribution of energies of the orbitals of slightly different energies so as to give a new set of orbitals of equivalent energies. The new orbitals are called hybrid or hybridised orbitals. The number of hybridized orbitals formed is equal t..

Quantum Mechanical Model of the Atom - Two new theories came to substantially modify Bohr's Atomic model. They a..

Wave nature of material objects In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Broglie's relation as: ..

The most popular hybridisation in carbon containing compounds are sp, sp 2 and sp ..

Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment) - The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolv..

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocity overrule..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of the h..

Mechanism of Racemisation - A compound where the chiral carbon atom is attached to a hydrogen atom and an electron-attracting group can undergo racemisation readily. The mechanism is enolisation. For e.g..
